Ahem, ignore that previous post please. Today I read in the paper that some jerks at the Scripps Institution of Oceanography in San Diego want to put a loudspeaker in the Pacific off Big Sur and Kauai that will broadcast a 195-decibel sound underwater every four hours for *twenty minutes* from now until 2004!!! This is in the March 22nd LA Times. As you know, whales communicate by sound and can, I think, hear pretty well, and it is already believed that underwater noise from ships cause whales and other marine life problems. As you also know, whales like to migrate along the California coast. This crappy idea was invented by Walter Munk of Scripps and is being funded by the Defense Department. The goal is to see how long it takes the sound to go from its point of origin across long distance through the ocean (the article hinted New Zealand), as a way of measuring the ocean temperature, to give us information about global warming. Now perhaps this is fine and dandy, but this idea gives me the creeps, and I hope people who know about this sort of thing don't let this experiment proceed without having a darn good understanding of the possible consequences. It sounds awful to me.
